Which amendment granted women the right to vote?

The 19th Amendment to the United States Constitution, ratified in 1920, definitively granted women the right to vote. This amendment was a significant milestone in the women's suffrage movement, which sought to secure equal voting rights for women. The achievement of the 19th Amendment marked the culmination of decades of activism, protests, and advocacy by women and their allies across the country who fought against the legal and social barriers to voting.

The significance of the 19th Amendment lies not only in its legal provisions but also in its broader impact on American society, as it transformed women's roles in politics and public life. Following its ratification, women began to engage more fully in the democratic process, contributing to the shaping of legislation and policy.

The other amendments listed do not pertain to women's suffrage. The 15th Amendment addresses voting rights for African American men, the 21st Amendment repealed Prohibition, and the 24th Amendment eliminated poll taxes in federal elections. Thus, the 19th Amendment is specifically recognized as the landmark legislation that secured voting rights for women in the United States.
